From c65b8555d5c002dfa102377849916327e05c7712 Mon Sep 17 00:00:00 2001
From: Stefan Tauner <stefan.tauner@alumni.tuwien.ac.at>
Date: Thu, 12 Sep 2013 15:48:39 +0000
Subject: BSD refinements

Make it easier to compile flashrom under NetBSD and DragonFlyBSD:
 - Use /usr/pkg/ as prefix for includes and linking
 - Use pciutils as include path for the right(tm) libpci

Also, fix date handling in getrevision.sh to work with the various formats for
invoking 'date'. This also uses svn's info --xml output instead of the regular one.

Corresponding to flashrom svn r1742.
